LM3433SQ/NOPB - TI Function Overview

The LM3433SQ/NOPB is a common anode capable high brightness LED Driver with high frequency dimming. It provides a constant current for illuminating high power LEDs. The output configuration allows the anodes of multiple LEDs to be tied directly to the ground referenced chassis for maximum heat sink efficacy. The high frequency capable architecture allows the use of small external passive components and no output capacitor while maintaining low LED ripple current. Two control inputs are used to modulate LED brightness. An analogue current control input is provided so the LM3433 can be adjusted to compensate for LED manufacturing variations or colour temperature correction. The other input is a logic level PWM control of LED current. The PWM functions by shorting out the LED with a parallel switch allowing high PWM dimming frequencies. High frequency PWM dimming allows digital colour temperature control, interference blanking, field sequential illumination and brightness control.
